Checkbox and Radio buttons activate on click-release to be consistent with other widgets and most UI

Fix clipboard pasting into an InputText box not filtering the characters according to input box semantic (number, etc.)

Activating widget bring parent window to front

Fixed clicking on Combo box label.

Avoid marking settings as dirty when window is marked unsaved + minor FocusWindow() optimisation

Dragging outside area of a widget while it is active doesn't trigger hover on other widgets.

Todo items.

InputText() consume input characters immediately (fixes #105)

Version number (fix)

Fixed text input filtering for character in the 128-255 range.

Fix for Clang

Examples: Console:: added support for History callbacks + cleanup to be self contained.

Fixed InputInt() InputFloat() label not declaring their width, breaking SameLine (bug #100) ...

+ shallow cleanups

crc32 on strings is performed in one pass - removed the strlen() call.

Version number

Style editor: added an Output button to output colors to clipboard/tty

Added SliderInt2(), SliderInt3(), SliderInt4() for consistency

Empty label consistently remove the inner-padding normally preceeding the label.

Tightening default style (saving -2 pixels on each axis per widget)

Log output \r\n under Windows so files are readable with Notepad

Log depth padding relative to start depth. Tree node and headers looking better when logged to text. Added LogText().

GetStyleColorName -> GetStyleColName for consistency with type name. Removed ImGuiStyleVar_ColumnsMinSpacing

Renamed GetTreeStateStorage() to GetStateStorage(). Columns storing floats instead of fixed point integers

Added LogFinish() to stop logging at an arbitrary point.

Minor fix for cases of malformed .ini file (zero-terminating text file like it was before previous commit).

Cleanup. Removed unnecessary calls to sqrtf(). Factoring bits into ImLoadFileToMemory(). Added index of static helpers.

Factoring bits out of Begin() into a private CreateNewWindow() funciton ...

(Hopefully to ease a bit the merging work for ProDBG)

CalcTextSize() default third parameter to false because it almost never makes sense to use it from the outside (may obsolete it)

Taking notes of issues/todo

Fixed clipped ImGui::Combo not registering its size properly (was flickering when scrolling with combo on the edge of clipping region)
